Bud Sr. and Mike (Bud's father and younger brother) travel to Washington for Bud and Harriet's wedding. Bud Sr. leaves insults, injuries, and hurt feelings in his wake; Harriet's mother also causes much discomfort and embarrassment. Bud passes a big career milestone with grace and empathy. A dry cleaner loses Harm's dress whites, but Harm finds them in an unusual place. The girls go to Harriet's party, then Mac bails Harm, Bud, and the admiral out of a DC jail after Bud's party. Bud Sr. skips the beautiful wedding, and Mike arrives late. Harm takes charge of a detail of eight officers who form an arch of swords for the new couple; he also shows up with an unusual and unexpected date.
